It depends on the type, model, made of the processor. Some of Intel Mobile processors (laptop processors) are embedded, some are not. Upgradeable or not depend on many factors, such as processor, motherboard/logic board, etc.

Based on my knowledge, embedded means soldered/attached on the motherboard/logic board and cannot be removed. Because of the limited space available on some laptop computers, some manufacturers have to choose this kind of processor.

You may find more information about those two types of processors and probably more information about the ECC memory. For some reasons, it doesn't matter if the processor supports ECC memory, the Apple laptop computer may or may not support that feature if the Apple doesn't want the laptop to support such feature, just like what they do with the 64-bit processing/kernel on most Apple laptop computers.

Dear CHB,
first of all thx for the answer...
After a ton of research, yesterday I've bought a 2,4 GHz i5 MacBookpro.
What I've understood in my search is this:
1) The possibility of upgrading the processor on MBP depends only on Apple strategy. In i5 MBP teardown the processor has been covered, so it is impossible to see if it is soldered on the MB. Anyway I remember that all the mobile processors used by Apple are soldered on the MB.
2) Before my search I agreed wiyh you about its meaning. But now I think that embedded means that the processors is also used as a component of other apparatus. So it doesn't mean soldered to the MB. Which physical difference exist between the i5 2,4 GHz and the i5 2,53 GHz? Why the first, that is defined embedded in its specs, should be soldered to the MB and the 2,53 GHz should not??? So, embedded only means that there are several other apparatus that use it.
3) i5 processors doesn't support ECC ram but the i5 520E.
What do you think about?
Regards,
Paci

Hi,
Anything is all about Apple's strategy, R&D (Research and Development), and technicians. I like the idea that Apple's technicians oversee the possibility and the future of hardware and technology for the sake of user's ease of use and satisfaction. I believe that allowing the end user to upgrade some hardware components or not, Apple's technicians have enough reason for that. It's NOT always about Apple's benefit to allow certain hardware upgrade. Of course, this is just my idea.
To be honest with you, I'm not really sure about the embedded processor technology. I think I need more research on that. Although, the processor might support the ECC memory, I think there might be more factors to get the computer to support ECC technology. Also, as I mentioned in my previous post, it might be up to Apple as well to allow such feature be supported by the computer.
Last but not least, Congrats for the new MacBook Pro you've just bought. I hope you enjoy it and have fun with it.
Regards,
CHB

It's time to speak out for your right to repair

Dear Minnesotans,

Right now, Minnesota has a chance to pass the first Fair Repair bill in the nation.
We have a chance to guarantee our right to repair electronics—like smartphones, computers, and even farm equipment.
We have a chance to help the environment and stand up for local repair jobs—the corner mom-and-pop repair shops that keep getting squeezed out by manufacturers.

We've been working with local repair companies, non-profit refurbishers, and tech-savvy politicians to come up with a solution. And they've done just that — Minnesota is the first state to consider a Fair Repair Bill.

If you agree with us, find out who represents you in the Minnesota House of Representatives.
Tell them you support the bipartisan Fair Repair Bill, HF 1048. Tell them that you believe repair
should be fair, affordable, and accessible.
